In semiconductor manufacturing, reliable communication between equipment and host systems is essential for productivity, compliance, and automation. SECS/GEM (SEMI Equipment Communication Standard / Generic Equipment Model) provides the foundation for this communication. However, validating SECS/GEM implementation on new or legacy equipment can be time-consuming and complex.
To address this, EINNOSYS has developed EIGEMSim, a powerful SECS/GEM simulator designed to help OEMs, fabs, and assembly/test facilities test and verify SEMI compliance. With EIGEMSim, engineers can simulate both equipment and factory host environments, making it an indispensable tool for development, integration, and testing.
What is EIGEMSim?
EIGEMSim is a software application that allows seamless testing of SECS/GEM communication. Depending on the use case, it can be configured to act either as the equipment or as the factory host. This flexibility enables teams to validate their integration scenarios without requiring a physical host system or equipment during early development stages.
The simulator supports creation, configuration, transmission, and receipt of SECS messages. To simplify operations, EIGEMSim uses a Message Dictionary, which facilitates message transfers and ensures accuracy in communication testing.
Creating and Configuring SECS Messages
One of the strengths of EIGEMSim is its flexibility in creating and configuring messages. Engineers can:
Use a built-in wizard that guides them step-by-step in defining SECS messages.
Or, write messages in SML (SEMI Markup Language) format using any text editor and then import the SML file directly into EIGEMSim.
This dual approach caters to both beginners and advanced users, providing efficiency and control during development. All messages sent and received are automatically logged, giving developers a complete record for analysis and troubleshooting.
Key Features of EIGEMSim
EIGEMSim comes packed with features that simplify SECS/GEM compliance testing and integration:
✅ Cross-Platform Support – Runs seamlessly on both Windows and Linux environments.
✅ Pre-Configured Messages – Includes the most commonly used SECS messages, helping users start compliance testing quickly.
✅ User-Friendly Interface – Intuitive design for easy configuration and message transmission.
✅ Dual Configuration – Can be set up as equipment or factory host, depending on the testing scenario.
✅ Comprehensive Logging – Records all incoming and outgoing messages for review, debugging, and documentation.
Why Choose EIGEMSim?
For OEMs and fabs, validating SEMI compliance is critical before deploying equipment in production environments. Traditional testing methods can be slow and require multiple hardware components. EIGEMSim removes these bottlenecks by providing a software-only, configurable simulator that reduces both time-to-market and testing costs.
With its ability to simulate different roles (equipment or host) and its ready-to-use message library, EIGEMSim accelerates development while ensuring compliance with SEMI SECS/GEM standards.
SECS/GEM integration is at the heart of modern semiconductor factory automation, and reliable testing tools are key to ensuring success. EIGEMSim by EINNOSYS empowers equipment manufacturers, fabs, and assembly/test facilities to streamline compliance testing, reduce complexity, and achieve faster integration.
Whether you’re developing new semiconductor equipment, upgrading legacy systems, or validating host communication, EIGEMSim offers the flexibility and reliability you need.
